Abstract (in English)

Archaeology’s main objective is the identification, characterisation and explanation of the history of humanity through material remains. The archaeological approach is called upon and directly involved in urban development projects. The city has a story; it has evolved over a long time which is marked physically in a space. Every planning project has a position with regard to these traces, in connection with the quest for meaning. There may be sanctuarisation of fragments of the city; traces can be erased, or else works on the traces can be considered as foundation for a planning project.
Archaeology can bring back traces of the past, with a vision that relies on reuse, integration of the archaeological remains within redevelopments, and knowledge of the evolution of cities as part of an urban project.
The three-dimension approach to a past magnified, from the knowledge of experiences and understanding of the site results in a specific economy and ecology. Regional knowledge allows the integration of a project within the diachronic structure of the site. It allows to further integrate the enduring elements of former societies into a future project.
Additionally, these approaches aim for the same goal, which is the integration of the past in order to build the future through education, and architectural or urban cohesion.
Heritage in its archaeological dimension is not only a driver for development, but above all an essential foundation for a sustainable urban development.
